It's a very good solution if you want to protect your data across two data centers, or you have a middle man or many administrators who use these solutions for protecting their data. It's very reliable compared to other solutions that are most often not storage-based.

We have not encountered any major challenges with replication. We were able to achieve near-real-time replication. Also, with the switchover failover, we were not getting any technical issues. It's a pretty stable product.

Data Guard also improved because customers with an active Data Guard license want to reduce the I/O in a production environment. Some application complaints to it for Oracle reporting purposes. It has a production environment that needs to be enhanced.

We have found the replication feature the most useful. We use this feature the most. The ability to recover a database with less effort and the use of Oracle Data Guard Broker to administer the complete environment are also very useful features.

We chose this solution for the availability of the databases. We can't afford Oracle Grid, this is the best solution if you want something similar that's less expensive.

There is an issue with their application on ODG. There were a lot of edits in the logs. Sometimes, we only get a little cue from the Data Guard Broker logs if there's an issue.

For Italian medium-sized companies, the main challenge lies in the cost associated with licenses.

One thing that can be improved is the GUI. It would be good to have a very nice GUI to easily configure and administer, providing different presentations to the database administrator. The feature that can be included is the integration with third-party monitoring systems, that is, monitoring systems from other vendors, not only from Oracle.

For every standby server you have, you must pay a licensing fee, which is the main disadvantage.

The usage of block storage devices in the cloud or migration of a type of storage from one site to another site can be improved. Currently, we have to use multi-node to single node because of the lack of storage support on the Azure side. It did not really work. Our DBA had to spend a lot of time tweaking the Data Guard tools, or the underlying Oracle VMs, to make sure that Data Guard would run on top of different types of storage. So, if it can support transporting or getting from one type of storage to another type of storage in a different site or a different technology, it would be very helpful.

A significant improvement for Oracle Data Guard would be enabling the disaster recovery site to handle read and write operations, not just data storage.

Oracle Data Guard is stable, but you need to keep monitoring the system all the time. You need to keep monitoring the archives.

When the data replicates into the standby database there is a possibility of having a microsecond amount of data loss. The data loss occurs when there is a network disconnection between the primary and secondary standby database located in the data centers or if there is a crash in the primary database.
